mitigations for the BGP vortex attack
by Martin Tonusoo 07 Oct '25

07 Oct '25

Hi. I recently read an interesting research paper that I don’t think has been shared here yet: https://www.usenix.org/system/files/usenixsecurity25-stoeger.pdf I would throw out two additional thoughts related to "Partial Mitigations"(6.1): 1. Usage of modern, multi-threaded routing daemons which are able to take advantage of multi-core control plane CPUs. 2. Control plane CPU usage monitoring. BGP per-neighbor sent and received UPDATE messages rate monitoring. For example, Junos supports this via SNMP, telemetry or RPC. In the "Safe BGP Communities"(6.2) paragraph the paper advises networks to cease the support of "Lower Local Pref Below Peer" community. As the BGP vortex forms only when both the "Lower Local Pref Below Peer" and "Selective NOPEER" communities are present, then perhaps alternative approach would be to cease the support of those two communities together. In other words, both communities would still be allowed separately, but not together. I did a brief analysis on RIPE RIS data for NTT, GTT and Sparkle "Lower Local Pref Below Peer" and "Selective NOPEER" type communities and the combination where both types are attached to the prefix are rare. Finally, I wonder if or how much the attack is amplified if the adversary ensures(for example, using communities) that each announced prefix has unique path attributes and thus there is an UPDATE message per prefix.

Note: Writing this felt like an Advertisement which is not the goal. I like to use documented open hardware[4] as do my peers so I am sharing it here. For my peers that rock Turris hardware you may like to know a new hardware platform was just announced Saturday[1]. The Webpage[2] is up and you can read detailed specs in the PDF[3]. If you follow software like BIRD and KNOT you may know about the Turris project already. TL;DR; 10gb SFP x2 2.5gb x4 Internal NVME slot Wifi 7 Fanless Color interface with d-pad 1. https://www.youtube.com/watch?v=PmbxCu-Yt7Q 2. https://www.turris.com/en/products/omnia-NG/ 3. https://secure.nic.cz/files/omnia_NG_listing_all/Documentation/Datasheet_mu… 4.

Best recommendation for out of band router access?
by Jonathan Kalbfeld 03 Oct '25

03 Oct '25

Hello, Obviously dial up is no longer practical for most applications. I have a some of my gear co-located in a facility in downtown Los Angeles where the idea of paying a monthly for a cross connect to get a phone line is just not practical. Can anyone recommend an idea that's not super cost prohibitive that would involve some kind of 4G or 5G Sim with a static IP address that is not CGNAT? I'm running OpenBSD for my Edge routers, so plugging in a USB is not guaranteed, so is there a product that might have some kind of a bridge functionality where it will establish a mobile IP connection and then plug into my switch? Also open to reasonably priced provider recommendations. I don't need a lot of bandwidth since this would mostly just be SSH or maybe openvpn traffic. If you know of service providers as well as recommended products, that would be ideal. I don't want to spend thousands, but a few hundred dollars on gear seems reasonable. Very best, Jonathan Jonathan Kalbfeld office: +1 310 317 7933 fax: +1 310 317 7901 home: +1 310 317 7909 mobile: +1 310 227 1662 ThoughtWave Technologies, Inc.

RFC8805 geofeed validation
by Yang Yu 01 Oct '25

01 Oct '25

Questions for folks ingesting geofeed, what do you use for address validation? Are non-ASCII characters supported, especially in City field? e.g. 부산 vs Busan What happens when Region field is empty? discard the line / use Country only / try to use Country + City (which may not be unique) Common parsing / validation errors? Thanks, Yang
